J. D. BLEVANS BOOT AND LINER FOR AUTOMOBILE AND SIMILAR CASINGS Filed NOV. 30. 1920 Patented July 3, 1923'.

To all whom it may concern:

Be it known that 1, JAMES L. D. BLEVANS, a citizen of the United States, Dallas, in the county of Dallas of T exas, have invented new and useful Improvements in Boots and Liners for Automobile and Similar Casings, of which the following isa specification.

This invention relates to boots or liners for automobile and similar casings.

The object of the invention is to provide a boot which is adapted to be used within the casing and is known as an inside boot in contradistinction to an outside boot which latter goes over the tread and side wall of the casing. Considerable trouble has been had with inside boots due to creeping, slippin and tube pinching. If the! inside boot is a lowed to move relatively of the casing and tube sufiicient friction will be set up to cause the tube to blow out, thus becoming a detriment rather than a help. Inside boots have been made with books for engaging the bead of the casing, but in applying the casing these hooks are often'displaced and caused to out the tube and also fail to hold the boot in place.

The object of my invention is to provide an. inside boot which is equipped with hooks adapted to engage the bead of the casing in such a manner that they cannot be displaced while in use, or while applying the casing to the rim. A further object is to provide hooks with long shanks so that they may be fastened to the boot a suitable distance inwardly from the edges thereof, whereby said edges may be reduced in thickness, thus causing the boot to better fit between the beads of the casing.

A particular object is to so form the hooks that after bein r engaged with the beads of the casing, said hooks cannot be displaced laterally, thus assuring a permanent positioning of the said boots. I v

Another object is to provide hooks in the nature of clamps, whereby the boot will be retained in place when the casing is removed from the rim.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompany- UNITED STATES PATEN v JAMES Ii. D. sLnvAns, on

w an example of the wherein:-

F1g. 1is a fragmentary view showing a ing drawings, in which portion ofv a rim, casing and .tube equipped;

with 'a boot constructed in accordance with my invention, 7

Fig. 2 is a perspective view of one end portion of said boot,

' Fig. 3 is an enlarged cross sectional view thru a rim andv tire equipped with said boot,

, and

Fig. 4 is a perspective view of one of the hooks. In the drawings the letter A designates an ordinary tire casing, B a boot constructed in accordance with my invention and H an formed of a number of fabric and suitably shaped. The adjacent edges of the boot are reduced so as to better fit in the casing A and a flap B is secured to the inside of the boot and lapped over the split between the edges thereof.

Inwardly from the longitudinal edges of the boot and on the outside thereof I secure suitable hooks C by means of rivets I. The hooks have long shanks so. that their retain- This boot may be layers of rubberized ing portions will be below the edges of the boot and the rivets at the top of-the hooks are set inwardly some distance from said edges and cannot readily pull out. Eachhook is bent at an angle, as is shown in Fig. 4: so as to conform to the cross sectional shape of the bead D of the casing. The head is provided with a bottom edge or surface E-and an outer surface F and the hooks are shaped so that their shank portions rest against the inner side of the bead, while their bottoms engage under the edge E and their lips at their outer ends engage the outer side F of said bead.

It will be seen that the boot B fits contiguous to the inner surface of the casing and the hooks snugly engage three sides of the bead of the casing. By this arrange ment the boot is held in place and the engagement of the hooks will be so tenacious that a tool will be required to disengage the same from the bead. It will be seen that after the boot has been placed in the casing 1 it cannot be displaced when the casing is inserted in the rim. Also the boot will not creep and, therefore, will reduce friction will be no out tube or pinched tube. The boot being on the inside is of great advantage as it will be protected by the casing and will wear very much longer, besides giving a smooth tread to the tire.

Various changes in the size and shape as Well as modifications and alterations may be made without departing from the spirit of the appended claim.

What I claim, is:

A boot for a tire casing having beads, metal hooks arranged upon the outer faces of the boot near its edges, each hook com prising an inner portion to engage the inner face of the bead, a base carried by the inner portion engaging the bottom wall of the bead, and an outer flange projecting upwardly from the base to engage the outer face of the bead, said hooks having interlocking engagement with the beads whereby the boot is held securely connected to the heads when the beads are spread during the insertion of the inner tube.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
